The Territorial legislature defined the boundaries and county seats for the West Slope in 1861.  Geographic knowledge of the Colorado mountains was somewhat limited at that time.  North Park (a name now synonymous with Jackson County) was an Indian hunting ground and little was known about it.

A boom started with the discovery of gold and silver at Teller City in 1879.  North Park was considered to be part of Grand County, and now there was property to assess and tax.  The Grand County road tax in North Park for 1881 applied only to males between the ages of 21 and 45.  They had to either pay $3 in cash or do two day's work on the roads. John Mills, a Teller City resident who acted as an attorney for mine owners, served as a Grand County commissioner and was one of the commissioners killed in the July 4, 1883 gun battle at Grand Lake.

As ranches became established and more mineral deposits were discovered, the Larimer County commissioners began to speculate that the "Snowy Range" that defined the western boundary of Larimer County was the Park Range on the west side of North Park rather than the Medicine Bow Range.  This opinion soon degenerated into a dispute between Grand and Larimer counties, ultimately ending up in court. In 1886 the Colorado Supreme Court ruled that North Park was part of Larimer County.

A trip to the county seat in Fort Collins was a considerable undertaking.  If everything ran on schedule it was possible for travelers to leave Walden on the morning stage, catch a train from Laramie to Cheyenne, another train from Cheyenne to Greeley, still another from Greeley to Fort Collins, and arrive at the county seat before closing hours the following day.  The fares amounted to a significant expense.  It was probably more common for a North Parker to travel to Fort Collins in his wagon, take care of business, and come home with a wagonload of provisions.  The trip by wagon took three to four days each way.

As the population of North Park grew, so did the desire to split from Larimer County.  In 1908 the Loveland newspaper stated that Larimer County was too big and advocated a new county with Loveland as the county seat.  The Walden newspaper agreed that the county was too big but felt the wrong division line had been picked, pointing out that "A Loveland man can get to the county seat in three hours anytime, but it takes a North Park man three days most of the time."

Ranchers resisted early efforts to set off the area west of the Medicine Bow Range into a county of its own as they carried the largest part of the tax burden and felt their taxes would increase if a new county was established.  But by 1908 there was general agreement within the Park that it was time for court and administrative offices to be more conveniently located.

The total valuation assessed in 1908 of North Park property by Larimer County was $771,776, which generated $16,979 of revenue.  The salaries of some of the paid officers of the new county was estimated as follows:

     Assessor                                                    $800

     County School Superintendent                   $800

     Water Commissioner, 2 districts                $1000

     County Commissioners                             $1000

Even adding in salaries for the sheriff and county clerk it appeared quite likely that the new county could be operated efficiently without a tax increase and the proposal to create "North Park County" had nearly unanimous support from North Parkers.  The bill passed the legislature easily in April 1909, with a name change to Jackson, and was quickly signed into law on May 5 by Governor Shafroth.

While North Parkers were eager to sever their legal ties to Larimer County in 1909, they clearly weren't ready to give up the pleasures of offered by a nip of the bottle.  Like most frontier areas, North Park had a significant number of single men who liked to occasionally get together and enjoy a few drinks with their friends.  Walden was the center of socialization.  According to an 1899 newspaper article, Walden residents worried about the "toughs" who came to town to "drink barbed-wire bitters and then shoot up the place."

In addition, local married men sometimes frequented the bars when they could have been spending more time at home helping out with domestic chores.  As a result, a strong temperance movement soon divided the community.  One of the two local newspapers, the North Park Union, endorsed the temperance movement in early 1902 and soon found itself the target of a boycott by both advertisers and subscribers.  Although the editor declared it a "boycott of no great magnitude", the paper had a new owner/editor within a month.  The issue of whether Walden should be wet or dry was on the 1902 ballot.  By a very decisive majority, voters decided Walden would continue to be wet.

Just before the 1906 election, the Walden newspaper criticized the local Republican Party bosses for providing a lot of free whiskey in every North Park precinct on election day, and urged North Parkers not to sell their vote for a drink.  The temperance movement enjoyed its first victory when it combined forces with the local church and convinced the businessmen of Walden to close their stores on Sundays.  The closing did not stand in high favor with ranchers.  "When a man can't buy axle grease for his wagon when it runs dry and something else for himself when he runs dry, it is time to call a halt," they declared.  Quite a number of the ranchers started going through to Laramie for their provisions, and the Sunday closing rule was abandoned six weeks after it was implemented.

When news reached Walden in early 1909 that the bill creating Jackson County had cleared the legislature, the newspaper reported that the town was moved to the point of a merry celebration.  The brass band marched, guns were fired, and at daybreak "the women, as becomes their sex, were among the few who were sober."  A few weeks later news that the Governor had signed the bill was cause for another celebration.  The newspaper reported that, "the air about town clouded up and filled with burnt powder and raucous vocalizations.  The festivities continued in the evening with flying anvils propelled by stick powder . . ." The first hundred years of Jackson County had commenced.

The principal population centers in the Fraser River Valley are Winter Park, Fraser and Tabernash.  When the early stage coaches came over Berthoud pass into the Fraser Valley, the most popular stop was at the Cozens Ranch, which now houses a historical museum in Winter Park. The valley is now bisected by U.S. Highway 40, which was designated the "Victory Highway" in 1931.  The new route of the highway leads through the main streets in both Fraser and Tabernash and the backdoors of some business became front doors because of the new highway alignment.   

Tabernash was the name given to a railroad siding, named for the Ute leader who was killed during a confrontation with local ranchers.  The town became a key station on the railroad line, and included a roundhouse, and a supply of helper engines for the steep climb over Rollins Pass.  When the Moffatt Tunnel was opened in 1928, the railroad no longer needed service there and the town lost its' main economic support.

George Easton founded the town site of Fraser in 1905.  The rest of the country became familiar with Fraser when the winter temperatures were often the lowest recorded in the U.S. and Fraser was know by the nickname "Icebox of the Nation".   Lumbering was one of the prime industries in the region until World War II.  During the war, the military built a Prisoner of War camp at Fraser to help lumber for the mills in the area.

The current area of Winter Park has had many names over the years.  First it was called simply "Old Town" or "Vasquez", named after the fur trader Louis Vasquez.  "Woodspur" or "Woodstock" referred to Billy Wood's lumber mill in the area, which furnished ties for the railroad while it was being built over Rollins Pass. During the construction of the Moffatt Tunnel, the name "West Portal" came into usage.  Rail workers also called the community "Little Chicago" as it was as it was a favorite gambling, saloon, and brothel site.  As tourists began to arrive it was known as "Idlewild" and also "Hideaway Park".  Finally, the name "Winter Park" was settled upon to correspond with the adjacent ski area of the same name.

The area population declined from 1232 people in the 1920's to only 373 people by 1930.  The Great Depression ended the construction boom and the price of beef became too low for ranches to turn a profit.  However, since that time, the area has thrived, mostly based on a tourism economy.  The valley's main source of income is now recreation and second home construction. 

Grand County is home to the headwaters of the famed Colorado River - the river that brings water to five other arid Western states.  Water is the lifeblood of semi-arid Colorado and Grand County is one of the most water-rich areas of Colorado, and yet faces a shortage due to historical water agreements, written long before population pressures and the environmental awareness of the current age.  On average, the water diversion projects in the county move a whopping 305,000 acre-feet per year from the Fraser, Colorado and Williams Fork rivers - all headwaters of the Colorado's main stem.

60 percent of the water in Grand County is diverted elsewhere and there are plans underway, mostly from Front Range communities, to divert as much as 80 percent of the county's headwaters by the year 2010.  Two of the main water utilities, Denver Water and the Northern Colorado Water Conservancy District face a quandary: how to take the water from Grand County without further damaging the delicate environment and the region's economy, which is fueled by tourists who expect to play in the very water the Front Range wants to take.

The idea of diverting water from the Colorado River on the Western Slope of the Continental Divide to the productive farmlands of the eastern plains had been a dream of planners as early as 1929.  Subsequently,  a long period of drought and the sagging economy of the “Great Depression” whetted demands for what became the largest trans-mountain diversion project ever built.

The Colorado-Big Thompson Project takes water from Grand Lake on the western side of the Continental Divide to the Big Thompson River on the east.  The water flows through a 13 mile tunnel beneath Rocky Mountain National Park.  In order to supply the residential and farming needs of Northeastern Colorado, the project was begun in 1938 and continued through the years of World War II.  The first water flowed though the tunnel, named for Senator Alva B. Adams, on June 23, 1947.

In order to assure an adequate supply from Grand Lake, a dam was built creating Shadow Mountain Reservoir.  A larger lake, Granby Reservoir was then built below, with a unique pumping plant that forces water into Shadow Mountain.  The Farr Pumping Plant cost over $9 million and provides an additional 700,000 of irrigated land to northeastern Colorado.  Further reservoirs were added, both to supplement the diversion and to compensate the water needs of Western Colorado.  These include Willow Creek and Windy Gap Reservoirs in Grand County.

While most legislators were enthusiastic about the project, U.S. Representative Edward Taylor was vehemently opposed to the reduction of water flowing down the Colorado River.  A compromise was reached in the creation of Green Mountain Reservoir (on the Blue River), which reserves water to replenish the Colorado River.   The city of Denver later claimed upstream water on the Blue River for the massive diversion project of Dillon Reservoir

Claims on the water of the Colorado River range from the fruit and wine regions of the Grand Valley in Colorado all the way to Los Angeles and Mexico.  It can be said that every snowflake which falls in Western Colorado had already been over-appropriated, especially during drought periods in the arid West.
